Description

Transmission method, configuration method, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method, a configuration method, a terminal, and a network device.

Background

In the prior art, after receiving a Physical DownLink Shared Channel (PDSCH) of a DownLink Semi-Persistent Scheduling (DL SPS), a User Equipment (UE) confirms a slot offset between a feedback slot of a Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) and a receiving end slot of the PDSCH according to a K value indicated by DCI or a default value at a network side, and generates and transmits an HARQ-ACK codebook based on the feedback slot.

However, there are three definitions of the transmission direction of the timeslot in NR, namely Downlink (DL), Uplink (UL), and flexible (flexible), and the transmission direction of the flexible timeslot can be modified by uplink and downlink configuration.

Therefore, determining the feedback slot based on the K value may not transmit the HARQ-ACK because the transmission direction thereof is modified, thereby causing the HARQ-ACK codebook to be discarded, and reducing the success rate of transmission.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

To facilitate an understanding of embodiments of the present invention, some related concepts are first described.

The HARQ-ACK timing is defined as an interval from the reception end time of downlink data to the time of corresponding acknowledgement/negative acknowledgement ACK/NACK feedback. NR supports flexible HARQ-ACK timing configuration for adaptation to different services and network deployments. Each UE may configure a UE-specific HARQ-ACK timing table through Radio Resource Control (RRC), where the table includes multiple HARQ-ACK timing values, referred to as K values, where K is a unit of a timeslot. When the base station dynamically schedules downlink data transmission, a value K is indicated in the DCI in an index mode, wherein the value K is a value selected from a UE-specific HARQ-ACK timing table and is used for informing the UE of the time for feeding back the HARQ-ACK.

If the DCI does not contain the value indicating the HARQ-ACK timing, the UE can determine the interval from the downlink data to the HARQ-ACK feedback according to the fixed value. For one DL SPS PDSCH sent in slot n, its corresponding HARQ-ACK is transmitted on slot n + K, where K is indicated in the DCI activating the DL SPS.

In order to implement flexible network deployment, in an NR system, the transmission direction of each symbol in one slot may be configured in a slot format (slot format).

The transmission direction of a slot in NR has three definitions: downlink (DL), Uplink (UL), and Flexible (Flexible). When the network configures a timeslot or a symbol to be DL or UL, the transmission direction at that time is definite, and when the network configures a timeslot or a symbol to be Flexible, the transmission direction at that time is pending. The network may modify the transmission direction of the time Slot or symbol of the Flexible through Dynamic signaling, such as a Dynamic timeslot Format Indicator (SFI). As shown in fig. 1, one slot may contain Downlink (DL), Uplink (UL) and Flexible (Flexible) Orthogonal Frequency Division Multiplexing (OFDM) symbols; the Flexible symbol may be rewritten as a downlink or uplink symbol.

The SFI may indicate a format of one or more slots, the SFI may flexibly change the format of the slots according to a requirement to meet a service transmission requirement, and the UE may determine whether to monitor the PDCCH according to the indication of the SFI.

The base station may semi-statically configure the UE with one or more cell-specific slot formats via a higher layer parameter UL-DL-Configuration-Common or UL-DL-Configuration-Common-Set2 (optional).

The base station may also semi-statically configure the UE with one or more UE-specific slot formats via a higher layer parameter UL-DL-Configuration-Dedicated.

The time domain resource format is also implicitly configured, as indicated implicitly by the measurements.

Referring to fig. 2, fig. 2 is a flowchart of a transmission method provided in an embodiment of the present invention, for a terminal, and as shown in fig. 2, the transmission method includes the following steps:

step 201, receiving a physical downlink shared channel PDSCH.

The physical downlink shared channel may be transmitted by a network side device, such as a base station.

Step 202, determining transmission parameters of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH according to a time domain resource format of transmission resources.

In the embodiment of the invention, in order to improve the transmission success rate of the HARQ-ACK, the transmission parameters of the hybrid automatic repeat request response (HARQ-ACK) codebook corresponding to the PDSCH can be determined according to the time domain resource format of the transmission resources, wherein the time domain resource format can indicate the transmission direction of the transmission resources in each time domain, so that a terminal can determine the time domain resources which can be used for transmitting the HARQ-ACK codebook through the time domain resource format of the transmission resources. For example, the time domain resource format may include three types of UL, DL and Flexible, and when the time domain resource format of a certain time domain resource in the transmission resources is determined to be UL, HARQ-ACK may be transmitted on the time domain resource.

Unlike the prior art, the method of the embodiment of the present invention determines the generation position of the HARQ-ACK codebook and/or the transmission resource by using the time domain resource format (or the transmission direction) of the transmission resource, rather than directly determining according to the offset value. Therefore, the method of the embodiment of the invention firstly determines the availability of the resources according to the time domain resource format of the transmission resources, or the method of the embodiment of the invention selects the available resources according to the time domain resource format of the transmission resources to process the generation and the transmission of the codebook, thereby reducing the problem of resource conflict and improving the transmission success rate of the HARQ-ACK codebook.

For the processing of the HARQ-ACK codebook, two aspects are included: and generating an HARQ-ACK codebook and a transmission HARQ-ACK codebook. In an embodiment of the present invention, the transmission parameters of the HARQ-ACK codebook may be applied to at least one of the above two aspects.

That is to say, in the specific embodiment of the present invention, the transmission parameter may be a time domain position parameter used for determining a HARQ-ACK codebook generation position, may also be a resource indication parameter used for determining a time domain transmission resource of the HARQ-ACK codebook, and may also include both the time domain position parameter and the resource indication parameter.

In other words, the transmission parameters can determine which time domain resource (e.g., slot) the HARQ-ACK codebook is generated on and/or determine which time domain resource (e.g., slot) the HARQ-ACK codebook is transmitted on.

Of course, the transmission parameter may also be other parameters that determine the HARQ-ACK codebook and are related to the resource transmission direction.

The method of the embodiment of the invention can be applied to the PDSCH scheduled in real time and can also be applied to the PDSCH transmitted based on the SPS (semi-persistent scheduling).

Compared with the existing mobile communication system, the future 5G mobile communication system needs to adapt to more diversified scenes and service requirements. The main application scenarios of the 5G New Radio (NR) include Enhanced Mobile Broadband (eMBB), large-scale internet of things (mm Type of Communication), Ultra-high Reliable Ultra-Low Latency Communication (URLLC), and these scenarios set forth requirements for the system such as high reliability, Low Latency, large bandwidth, and wide coverage.

These different scenario services have different Quality of Service (QoS) requirements, for example URLLC supports low latency, high reliability services. To achieve higher reliability, data needs to be transmitted using a lower code rate, and faster and more accurate feedback of Channel State Information (CSI) is needed. The eMBB service supports the requirement of high throughput, but is less sensitive to latency and reliability than URLLC. In addition, for some UEs which may support services with different numerical configurations (numerology), the UE supports both URLLC low-latency high-reliability services and high-capacity high-rate eMBB services.

For a service which occurs periodically and has a fixed data packet size, in order to reduce the overhead of downlink control signaling, the network side may continuously allocate a certain resource for the transmission of the periodic service in a semi-persistent scheduling manner. This manner of Semi-Persistent Scheduling in DownLink is called DL SPS (DownLink Semi-Persistent Scheduling), which can reduce the overhead of Scheduling a periodically transmitted and small Voice over Long-Term Evolution (VoLTE) Voice packet, thereby making more resources available for Scheduling additional UEs.

The network side can configure parameters required by DL SPS for the UE through high-layer signaling, such as period, HARQ process number of hybrid automatic repeat request, HARQ-ACK feedback resource and the like. After the UE configures the DL SPS configuration, the base station may activate the configured DL SPS configuration through Downlink Control Information (DCI), where the DCI includes transmission parameters such as a DL SPS transmission resource and a Modulation and Coding Scheme (MCS). The UE determines the time instant of DL SPS transmission and the frequency resources at the corresponding time instant by receiving the activation DCI. At each DL SPS time, the UE will listen for a corresponding data transmission on the DL SPS resources.

However, for the PDSCH based on semi-persistent scheduling SPS, it is scheduled for the channel and fed back for HARQ-ACK using the same configuration for a certain time. During the period, due to the change of various network states or the need of traffic scheduling, etc., the probability that the transmission direction of some transmission resources is changed is relatively high, and the probability that the HARQ-ACK codebook corresponding to the PDSCH based on the semi-persistent scheduling SPS is discarded is higher.

Therefore, the method of the embodiment of the invention is applied to the PDSCH transmitted based on the semi-persistent scheduling SPS, and can effectively improve the transmission success rate of the HARQ-ACK codebook.

The method of the embodiment of the invention can be directly applied to the feedback of the HARQ-ACK codebook, but can also be combined with the feedback of the HARQ-ACK codebook in the prior art, and the transmission parameters are determined again under the condition that the transmission resources determined by applying the prior art can not feed back the HARQ-ACK codebook.

In this way, the step 202 specifically includes:

under the condition that a feedback time slot can not transmit the HARQ-ACK codebook, determining transmission parameters of a hybrid automatic repeat request (HARQ-ACK) codebook corresponding to the PDSCH according to a time domain resource format of the transmission resources, wherein a time slot offset value between the feedback time slot and a receiving time slot of the PDSCH is K; the K is indicated by Downlink Control Information (DCI), or the K is a default value.

It can also be said that the step 202 specifically includes:

determining a feedback time slot of the PDSCH; a time slot offset value between the feedback time slot and the receiving time slot of the PDSCH is K; the K is indicated by downlink control information DCI, or the K is a default value;

and under the condition that the feedback time slot can not transmit the HARQ-ACK codebook, determining the transmission parameters of the hybrid automatic repeat request HARQ-ACK codebook corresponding to the PDSCH according to the time domain resource format of the transmission resources.

And whether the feedback time slot can transmit the HARQ-ACK codebook or not can be determined according to subsequent semi-static uplink and downlink configuration, dynamic uplink and downlink configuration and the like.

In this embodiment, the terminal may preferentially determine a feedback time slot based on a value K, which is a value of a HARQ-ACK timing sequence indicated by DCI, or a default value K, and generate and transmit the HARQ-ACK codebook on the feedback time slot, where a time slot offset value between the feedback time slot and a receiving time slot of the PDSCH is K, so that the feedback time slot may be determined according to the receiving time slot and K of the PDSCH.

If the HARQ-ACK codebook cannot be transmitted in the feedback time slot, if the feedback time slot is modified to a downlink format, the aforementioned method for determining the transmission parameters of the HARQ-ACK codebook corresponding to the PDSCH according to the time domain resource format of the transmission resources may be further adopted to determine the time domain position for generating the HARQ-ACK codebook and the time domain transmission resources for transmitting the HARQ-ACK codebook.

For example, the feedback time slot is a DL time slot indicated by the semi-static uplink and downlink configuration (that is, the time slot does not include uplink resources), and at this time, it may be determined that the feedback time slot cannot be used for transmitting the HARQ-ACK codebook. If the feedback time slot is a DL time slot indicated by the dynamic uplink and downlink configuration signaling (that is, the time slot does not include uplink resources), it may also be determined that the feedback time slot cannot be used for transmitting the HARQ-ACK codebook.

In an embodiment of the present invention, the availability of resources is determined according to a time domain resource format of transmission resources, or in other words, the method in the embodiment of the present invention selects available resources according to the time domain resource format of the transmission resources to process generation and transmission of a codebook, and the time domain resource format of the transmission resources may be determined according to various manners, for example, according to time domain resource format configuration information or resource usage configuration information.

That is, the step 202 may include:

and determining the transmission parameters of the HARQ-ACK codebook corresponding to the PDSCH according to target transmission resources, wherein the target transmission resources are determined according to time domain resource format configuration information or resource use configuration information.

In the specific embodiment of the present invention, the time domain resource format configuration information may be understood as an explicit time domain resource format of the transmission resource, and the resource usage configuration information may be understood as an implicit time domain resource format of the transmission resource.

In this embodiment, the transmission parameters of the HARQ-ACK codebook corresponding to the PDSCH may be determined according to target transmission resources, where the target transmission resources may be determined by two different resource configuration information, and the two manners are described below:

the first is to determine the target transmission resource according to resource usage configuration information. The resource usage configuration information may be information configured by the network side device to indicate usage of each transmission resource, for example, the network side device may configure usage of each transmission resource, such as a resource configured to transmit uplink data/signaling, or configured to transmit downlink data/signaling, or configured to transmit HARQ-ACK, so that the terminal may determine a target transmission resource according to the resource usage configuration information.

That is to say, the target transmission resource may include a first time domain resource, where the first time domain resource includes a time domain resource configured by a network side device for HARQ-ACK feedback, so that a terminal may transmit the HARQ-ACK codebook on the time domain resource for HARQ-ACK feedback.

The second method is to determine the target transmission resource according to Time domain resource format configuration information, where the Time domain resource format configuration information may be Time Division Duplex (TDD) configuration information of semi-static configuration, or may be configuration information in a dynamic configuration signaling.

The semi-static uplink and downlink configuration may indicate a format of each time domain resource, such as an uplink resource, a downlink resource, or a flexible resource, so that the time domain resource format may be determined to be an uplink target time domain resource through the semi-static uplink and downlink configuration. The dynamic configuration signaling may also indicate the format of each time domain resource, so that the terminal may also determine the time domain resource format as an uplink target time domain resource through the dynamic configuration signaling.

Of course, the terminal may also determine that the time domain resource format is the target time domain resource of the uplink through the semi-static uplink and downlink configuration and the dynamic configuration signaling configuration at the same time.

That is, the target transmission resource may include a second time domain resource and/or a third time domain resource, wherein the second time domain resource includes: the time domain resource format indicated by the semi-static uplink and downlink configuration is uplink time domain resource; the third time domain resource includes: and the time domain resource format indicated by the dynamic uplink and downlink configuration signaling is uplink time domain resource. In this way, the terminal can determine the time domain resource with the time domain resource format being uplink through the second time domain resource or the third time domain resource, and transmit the HARQ-ACK codebook on the time domain resource.

Considering the execution time of the dynamic uplink and downlink configuration signaling, in order to make the network side device and the terminal have a unified understanding, in the specific embodiment of the present invention, it may be required that: the receiving time of the dynamic uplink and downlink configuration signaling and the time interval of the third time domain resource in the time domain are greater than or equal to preset values.

When the target transmission resource is a third time domain resource, the time interval between the receiving time of the dynamic uplink and downlink configuration signaling and the time interval of the uplink time domain resource in the time domain, which is indicated by the dynamic uplink and downlink configuration signaling, is greater than or equal to a preset value.

That is, the time slot position of the target transmission resource is at least the distance from the time of receiving the dynamic uplink and downlink configuration signaling to the preset value, and the terminal will start to transmit the HARQ-ACK codebook after receiving the dynamic uplink and downlink configuration signaling for at least the preset time length. In this way, it can be ensured that enough time for processing the dynamic uplink and downlink configuration signaling or the PDSCH channel is reserved for the terminal.

Optionally, the first time domain resource is associated with at least one PDSCH transmission opportunity, and an offset value of the first time domain resource and the at least one PDSCH transmission opportunity in a time domain is greater than or equal to K time units; the K is indicated by downlink control information DCI, or the K is a default value.

When the target transmission resource includes a first time domain resource, that is, a time domain resource configured by a network side device and used for HARQ-ACK feedback, the first time domain resource may be associated with at least one PDSCH transmission opportunity (occupancy), and an offset value of the first time domain resource and the at least one PDSCH transmission opportunity in a time domain is greater than or equal to K time units, so as to ensure that the terminal has enough time to demodulate the received PDSCH channel, and avoid that the terminal cannot correctly transmit the HARQ-ACK without processing the completion of the PDSCH.

The time unit may be a time slot or other units, such as a micro-slot, a symbol, etc.

As already mentioned before, the transmission parameters comprise at least one of the following parameters: a time domain position parameter for indicating a generation position of the HARQ-ACK codebook, and a resource indication parameter for indicating a time domain transmission resource of the HARQ-ACK codebook.

The following specifically describes the determination of the time domain location parameter and the resource indication parameter in conjunction with the target transmission resource, as follows:

the target transmission resource is a transmission resource which can be used for transmitting the HARQ-ACK codebook, and the time domain position indicated by the time domain position parameter is a time domain position corresponding to the target transmission resource;

or

The target transmission resource is a transmission resource which can be used for transmitting the HARQ-ACK codebook, and the time domain resource indicated by the resource indication parameter is the target transmission resource;

or

The target transmission resource is a transmission resource which can be used for transmitting the HARQ-ACK codebook, the time domain position indicated by the time domain position parameter is a time domain position corresponding to the target transmission resource, and the time domain resource indicated by the resource indication parameter is the target transmission resource.

That is to say:

the target transmission resource may be a transmission resource capable of being used for transmitting the HARQ-ACK codebook, and when the transmission parameter includes a time domain position parameter, a time domain position indicated by the time domain position parameter is a time domain position corresponding to the target transmission resource, and the terminal may generate the HARQ-ACK codebook at the time domain position corresponding to the target transmission resource.

The target transmission resource may be a transmission resource which can be used for transmitting the HARQ-ACK codebook, and when the transmission parameter includes a resource indication parameter, the time domain resource indicated by the resource indication parameter is the target transmission resource on which the terminal may transmit the HARQ-ACK codebook.

The target transmission resource may be a transmission resource capable of being used for transmitting the HARQ-ACK codebook, when the transmission parameter includes a time domain position parameter and a resource indication parameter, the time domain position indicated by the time domain position parameter is a time domain position corresponding to the target transmission resource, and the time domain resource indicated by the resource indication parameter is the target transmission resource, and the terminal may generate the HARQ-ACK codebook at the time domain position corresponding to the target transmission resource and transmit the HARQ-ACK codebook on the target transmission resource.

When the target transmission resource includes a first time domain resource (a time domain resource configured by the network side device for HARQ-ACK feedback), the slot format of the first time domain resource may also be reconfigured by the network side device, so that the first time domain resource cannot transmit the HARQ-ACK codebook. In this case, in order to avoid the problem of inconsistent understanding between the network side device and the terminal, the generation of the HARQ-ACK codebook is directly abandoned, or the transmission of the HARQ-ACK codebook on the target transmission resource is abandoned.

That is, after the step 202, the transmission method further includes:

when the time domain resource format of the target transmission resource conflicts with the time domain resource format indicated by the uplink and downlink configuration, at least one of the following operations is executed: and giving up the generation of the HARQ-ACK codebook at the time domain position corresponding to the target transmission resource, and giving up the transmission of the HARQ-ACK codebook at the target transmission resource.

The time domain resource format of the target transmission resource conflicts with the time domain resource format indicated by the uplink and downlink configuration, which can be understood as a case that the target transmission resource is additionally configured as a time domain resource of a downlink DL or a Flexible flex by the network side device. In this case, since the target transmission resource cannot transmit the uplink resource, the terminal may give up generating the HARQ-ACK codebook at the time domain position corresponding to the target transmission resource, and/or give up transmitting the HARQ-ACK codebook at the target transmission resource.

In a case that the target transmission resource includes a first time domain resource (a time domain resource configured by the network side device for HARQ-ACK feedback), the configuration information of the first time domain resource may be sent to the terminal by the network side device. That is, in the case that the target transmission resource includes a first time domain resource, the transmission method further includes:

receiving a configuration message, wherein the configuration message is used for indicating the first time domain resource.

In this embodiment, the target transmission resource may be indicated by a network side device by issuing a configuration message, that is, the network side device may send a configuration message for indicating the first time domain resource to the terminal, and the terminal may receive the configuration message, and further may determine, by using the configuration message, the time domain resource configured by the network side device and used for HARQ-ACK feedback, and transmit the HARQ-ACK codebook on the time domain resource.

Wherein the configuration message indicates the first time domain resource by a first parameter set or a second parameter set;

the first parameter set includes: a period parameter indicating a repetition period of the first time domain resource; and a first location parameter for indicating a time domain location of the first time domain resource within a period;

the second parameter set includes: a period parameter indicating a repetition period of the first time domain resource; and a second location parameter indicating a time domain offset value of the first time domain resource relative to a cycle boundary.

The configuration message may indicate the first time domain resource in two different ways, one of which is indicated by a first parameter group, which may include: the resource allocation method comprises a period parameter and a first position parameter, wherein the period parameter is used for indicating a repetition period of the first time domain resource, and the first position parameter is used for indicating a time domain position of the first time domain resource in one period. That is to say, the network side device may configure a period of HARQ-ACK feedback time domain resources, and in a time region of one period, indicate a time domain resource position for HARQ-ACK feedback in the period in a bitmap (bitmap) manner, so that the terminal may determine, according to the first parameter group, a time domain resource position for generating and transmitting the HARQ-ACK codebook in each period.

The second parameter group is indicated by the second parameter group, and the second parameter group may include: and similarly, the period parameter may be used to indicate a repetition period of the first time domain resource, and the second position parameter may be used to indicate a time domain offset value of the first time domain resource relative to a period boundary, that is, a reference point of the time domain offset value is a boundary of a period, and a time domain resource position for HARQ-ACK feedback may be determined according to the period and the offset value within the period, so that the terminal may determine a time domain resource position for generating and transmitting the HARQ-ACK codebook in each period according to the second parameter group.

In the embodiment of the present invention, the terminal may be any device having a storage medium, for example: terminal devices such as computers (Computer), Mobile phones, Tablet Personal computers (Tablet Personal Computer), Laptop computers (Laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), and Wearable devices (Wearable Device).

How to determine the generating position of the codebook and the transmission resource of the codebook by the method of the embodiment of the present invention is further illustrated in the following with reference to specific timeslot numbers.

Assuming that the UE receives at least one DL SPS PDSCH slot n-n + X, if the semi-static uplink and downlink configuration indicates that slot n + K-n + X + K is DL or flexile, the UE determines the generation position of the HARQ-ACK codebook according to HARQ-ACK feedback resources (i.e., first time domain resources) configured by the network side device.

Example 1:

let K be 1 slot.

The UE configures cell-specific TDD configuration information indicating a slot format as shown in fig. 3.

The network side device configures the feedback time domain position of HARQ-ACK for the UE, and is used to determine a HARQ-ACK codebook, which is slot #5 and slot #10 as shown in fig. 3.

The UE determines to generate a HARQ-ACK codebook 1 at slot #5 according to the feedback time domain position of the HARQ-ACK configured by the network side equipment, wherein the HARQ-ACK codebook 1 is associated with SPS PDSCH occase #1 to SPS PDSCH occase #4 (because the time interval between the slot where the PDSCH occase #1 to SPS #4 is located and the slot #5 is greater than or equal to K).

In addition, the UE determines to generate a HARQ-ACK codebook 2 in slot #10, wherein the HARQ-ACK codebook 2 is associated with SPS PDSCHs #5 to # 9; (although SPS PDSCH occase #5 collides with slot format and PDSCH may not be transmitted, this embodiment still needs to associate the PDSCH occase when generating HARQ-ACK codebook).

Example 2: the UE configures cell-specific TDD configuration information and indicates that all time slot formats are Flexible; or the UE is not configured with the cell-specific TDD configuration information, that is, the UE considers all slots to be in Flexible format.

Assuming that the UE receives at least one DL SPS PDSCH in slot n-n + X, if the slot n + K-n + X + K is DL or flexile, the UE determines the generation position of the HARQ-ACK codebook according to the UL resource indicated by the dynamic uplink and downlink configuration signaling after the slot n + K-n + X + K, wherein the time interval between the UL resource indicated by the slot format and the dynamic signaling indicating the slot format is greater than or equal to a preset value T.

And the UE feeds back the time domain position according to the HARQ-ACK configured by the network side equipment. Since slot #5 is not the feedback time domain position of the HARQ-ACK configured by the network side device, PUCCH 1 carrying HARQ-ACK codebook 1 is not sent; and the UE determines the PUCCH resource for transmitting the HARQ-ACK in slot #10 and transmits PUCCH2 carrying HARQ-ACK codebook 2.

And assuming that the UE receives at least one DL SPS PDSCH in slot n-n + X, if the semi-static uplink and downlink configuration indicates that slot n + K-n + X + K is DL or flexile, the UE determines the transmission resource of the HARQ-ACK according to the UL resource indicated by the semi-static uplink and downlink configuration after slot n + K-n + X + K.

And assuming that the UE receives at least one DL SPS PDSCH in slot n-n + X, if the dynamic uplink and downlink configuration signaling indicates that slot n + K-n + X + K is DL or flexile, the UE determines the transmission resource of the HARQ-ACK according to the UL resource indicated by the dynamic uplink and downlink configuration signaling after slot n + K-n + X + K.
